User questions & answers

Question:	Will this work in India/ Europe
Answer:	Yes, this meter will work anywhere in the world. This one version will measure both 50 and 60Hz power regions.
Question:	Will this pick up UHF and microwave
Answer:	Thank you for your question. This meter will detect all three types of electromagnetic pollution.; AC magnetic, AC Electric and RF/Microwave.
Question:	Does this pick up emf/rf at a distance, or do you have to hold it right next to the source
Answer:	This meter will pick up EMF/RF at any distance, as long as the field is strong enough.
Question:	Does this read digital RF from cellphone towers, wifi, wireless LAN, etc
Answer:	The TF2 RF section is great for measuring the EMF emissions of cellphone towers, Wi-Fi and mobile phones. When reading RF emitted by digital devices, such as mobile phones, Wi-Fi routers and smart meters, the Peak Measurement (small numerals in the upper-left of the display) is of more interest than the Field Measurement (large numerals at the bottom). The information from digital RF devices is transmitted in brief packets that occur irregularly (perhaps once per minute with smart meters and several times per second with Wi-Fi transmitters or mobile phones that are in use). The Peak Measurement detects these packets and displays the strongest packet for several seconds before resetting itself.

User questions & answers

Question:	What's the difference between this and $300+ rf meters? my 13yo son is doing a science fair project on cell phone radiation. thanks
Answer:	This EMF meter measures 60 Hz (up to 300 Hz) frequencies. That's basically power line type electro-MAGNETIC radiation. The cell phone radiation is RADIO frequency radiation in the Mega or Giga-Hz range. So, this meter will not work for his project.
Question:	Can this be used to detect electrical radiation from electrical boxes on the side of the apartment building where we are living? we are concerned that there might be a lot of electrical toxicity coming from that into our unit
Answer:	Yes, but it only detects EMFs. There is no such thing as electrical toxicity, but there is ionizing radiation, from high voltage electrical fields, or high strength magnetic fields, hence electromagnetic field. Just look up the current data for recommended levels of exposure, then set the meter for that level. Then examine the areas you occupy for the length of time required for exposure limits. If you exceed the limits, replaced the device causing the problem, or relocate the occupied area for less total time. Another comment talks of all the different devices. I can tell you right now, every single AC device produces EMF. All of them. It's not about whether you are exposed, it about how much, and for how long. The alarm clock thing has been known for over 40 years. Just like CFLs if used within less than 15in is cancerous.
Question:	Can it be used to detect ghosts
Answer:	This will not detect ghosts, even if you believe it will. This detects electro magnetic fields. So unless you believe ghosts are produced every second by electricity, the Earth is surrounded by a ghost, and everyone's phone houses ghosts, this will not help you.
Question:	Has anyone had a professional come and collaborate your reading from this meter
Answer:	Yes. I tested it with calibrated equipment. It reads 0.0 milligauss up to 1.6 milligauss of ambient magnetic field. In other words, you might think there's no field when the meter reads zero, even though there could be as much as 1.6 mG present. At higher fields, it actually reads 2.5x too HIGH (reads 250 in a 100 mG field for example)). WAY inaccurate. Also the confused "English" manual claims it also reads "electric" field. It doesn't. And it doesn't read RF, microwaves, cell towers, etc. either. However, the meter is poorly shielded, so when placed near a leaky microwave oven, the meter circuit is interfered with, and it sometimes reads something, although the number is meaningless.

User questions & answers

Question:	Can it be plugged in to external power
Answer:	No, this EFM Meter can not be plugged into an outer power source.
Question:	I'm a person with ehs, i want to know if this meter might be good to read the radiation from cellphones, high tension lines, cell phone towers, 5g? ty
Answer:	Honestly, you probably could read the output of them in Milligauss or Microtesla but you would have to get pretty uncomfortably close. For reading radiation of those things and not endangering yourself I imagine you would need a pretty powerful EMF Meter. After doing some quick research on this, you would need something along the lines EMF Detector with the detectable range of something like 10 Hz to 10-12 GHz. For radiation coming from Cell towers you will be in the 50-10,000 MHz Radiation from high tension lines you will be looking at under 5 MHz by a great deal
Question:	Can it detect the variables in earth's magnetic field
Answer:	Thinking logically about it you would think yes because weather it be earth's magnetic field or a magnetic field from say inside your house from an appliance they would both be detected. But that is just my thoughts about it so you would need an answer really from the manufacturer.
Question:	Can this device detect radiation from nuclear fallout
Answer:	no

User questions & answers

Question:	Will this measure the radiation level present in gemstones
Answer:	Not all gemstones emit high enough levels of radiation that can be discerned above ambient levels of radiation and it depends on the actual level of radiation the stone emits. Stones that have been exposed to radiation to change their color will probably not register. I have some uranium marbles that are not detected by this counter. My wife was subjected to a PET scan, last year and read 790 CPM from a distance of 6 feet.
Question:	can I use this to measure Fukushima radiation in seafood
Answer:	I've read articles regarding radiation in seafood indicating the levels you read may be may be misleading. The GMC-300 will measure this radiation. Here in Northern Indiana the ambient level is normally 30 - 40 CPM. As shown in the video, levels in sea life can be higher. http://www.opb.org/news/article/scientists-say-stop-worrying-about-fukushima-radio/ Rick
Question:	I'm a novice wanting to check for radiation levels. Is this device easy to understand? What can I use this for to measure for radiation
Answer:	The GMC-300 is easy to use and low priced as an entry level radiation detector. I use mine to monitor background levels of radiation as I have yet to find an highly active source. Here in central BC, Canada I get 14 to 22 cpm, with a high of 30 cpm. It appears to decrease after a rain fall. The only thing missing with the GMC-300 is a radiation standard but I can understand why.
Question:	Would this device be able to tell if there was leftover radiation from a nuclear blast or contamination? Or radiation from dirty bombs
Answer:	I’m a radiation protection technician. If this device works the way that it says it does then it would still not detect alpha or neutron radiation. If you suspect something making into your food or water then I would be most concerned with Alpha particles and this doesn’t measure those. You shouldn’t have to worry about neutron radiation though and unless you’re using it to measure something you’re ingesting then alpha radiation really isn’t an issue. Geiger- Mueller counter can detect beta and gamma/X-ray radiation. I’d be interested to see how they measure Beta since you really need a gas chamber to measure it accurately. I would be most worried about beta and gamma radiation if you’re talking about an area that may have had nuclear weapons detonates years ago. This claims it can measure for those. If it can it would be a good device to determine if your surroundings are still giving off radiation.

User questions & answers

Question:	What is the frequency range of this device
Answer:	Hello Rafael, Thanks for reaching out to us! Frequency range is 50hz to 3000Mhz. Please let us know if there's any other way we can help. Kind regards, Sherrylyn Customer Service, American Lifetime
Question:	how many does this come with
Answer:	One, and its very entry level. I would recommend a trifield meter or something more advanced instead.
Question:	Hello, is it work for detecting smart meter radiation level
Answer:	Yes, it should detect a magnetic field similar to WiFi. It will only detect the smart meters electrical field when close by. Word of advice, if you buy this meter do not power on the unit close by what may be putting off these fields. Instead, power on the detector further from any other signals then walk towards what you want to measure.
Question:	Is this also an rf device or strictly an emf device? my understanding is emf is electrical and rf is radio frequency like wireless
Answer:	While this is a great way to count the emf power. Some of who are interested in radio have been using an alternate solution for the last 60 years. Simply tune a portable AM radio to an unused. quiet spot on the dial. Turn the volume up, then walk around your home or plant and "listen" to the EMF. Use the radio like a Geiger counter to point toward the offenders. You can actually hear the differences, and rate intensity by the loudness of the sound. Interestingly, some will have a buzz, some while whine, some will pulse, some will gurgle. Some will radiate a foot or less, some will radiate 6 feet or more. Interesting to listen to the difference between a wireless phone charging pad when the phone is on and then off the pad. The same can be done in your car, with the radio tuned to a quiet "AM" spot as you drive past power transformers, overhead high tension power lines and etc. During electrical storms, you can pick up lightning from more than 100 miles away as a sharp "crackle". If lighting is closer, count the seconds from the "crackle" until you hear the boom to calculate the distance in miles. Still a device like the Cambridge Labs EMF meter are very useful, but there are interesting ways to compliment it or even without it by using portable AM radios. Some of us have been using this AM system for many years to route out interference to our shortwave radios and etc since the late 1950's!

Product description

User questions & answers

Question:	This only looks like it protects outside your home. what protects inside
Answer:	Under “Features & details,” it states: EFFECTIVE: Shields your entire home by blocking ~98% of Smart Meter EMF, RF radiation. You will need a meter to determine if further measures are needed, but it sounds like they won’t be.
Question:	Has anyone measured the waves with and without this cover on their meter
Answer:	Yes the meter was 160 190 with cover 24 to 30 with a emf reader, i have had mine for a month and everday the electric company recieves its signal as should, my ears would ring so bad after using my back room bathroom it would make me fill sick to stomach. I can still hear them ring at times but it seems to now be more dependant on the electrical use and not a constant just because of the meter. This cover is worth it.
Question:	Can you make a video like your competitor to see that it works effectively
Answer:	Good suggestion - we did add pics to the listing, but will add a video shortly.
Question:	Could this be worn as a hat to replace my foil one
Answer:	Yes. It is definitely as large as a hat.

User questions & answers

Question:	Is there a way to turn off the alarm / sound
Answer:	yes, I think momentarily pressing the power button will do this (the alarm toggles on and off using the power button)
Question:	I stood on my deck and pointed the tester towards the power lines by my house. i did not get any readings emf showed 0. is this conclusive
Answer:	If the power lines are far enough away and not transmitting a high current load you shouldn't get a reading. The big huge transmission towers can show high levels of EMF. The lines to your home shouldn't show much. Old fluorescent lights and old CRT monitors can leak a lot of it.
Question:	can you test soil

User questions & answers

Question:	Why are reading alot higher when held in my hand versus setting on table (ball not touching anything)? also why read higher on Y axis
Answer:	Hello, The reason for higher reading might be that your body serves as an antenna or a reflector of the signal back to the meter. Please ensure that your cell phone turned off when you do the measurements.
Question:	Will this meter measure the frequency from a high voltage power line running in front of our land? Need to know how far to build for it to be safe
Answer:	Hello, The HF-B3G won't measure low frequency EMF. In order to do so we recommend you using the MG-300 or the MG-2000T. https://www.amazon.com/dp/B01CGVBP5O https://www.amazon.com/dp/B01HQBRZ9O
Question:	Does this emit any kind of rf itself? i am highly sensitive to wi-fi radiation. it effects my heart condition. so can't have anything that emits it
Answer:	Hello,The RF Meter is only measure the RF signals. It does not emits RF.
Question:	What kind of battery does this use? Is it internal and rechargeable or do you place the batteries inside and if so, what size / type battery? Thanks
Answer:	I am sorry for the delay in my answer. This device uses regular 9v battery (comes with it). You can use any rechargeable 9v battery. But, before you buy this device, I need to let you know that I find it to be no so accurate. The numbers keep jumping up and down, in high values, making the device useless. It has a way to lock on the max value, but does not show the real time number. I am going to send the supplier an email asking them if this is expected. I used to have an analog one, and it showed some small/ minute variation in readings, but still manageable. I bought this digital device, because I thought I can get a better, accurate reading. This might be more detail than expected, but hope it is useful.

Product description

Proudly made in the USA the Smart Meter Guard blocks EMF Radiation, including the new 5G!



The Smart Meter GUARD is the original smart meter shield, invented by us. Tested and proven to block up to 98% of the EMF your smart meter emits. We have over 20 years’ experience in RF/EMF technology and know how to shield and block the EMF your smart meter is emitting.



! Be aware of crude copies made in China that leak EMF. See our Youtube video that shows the Smart Meter Covers leaking. If you install these Chinese made copies you are still exposed to EMF.



The Smart Meter Guard is the "first" and "highest quality" shield that effectively blocks 98% of the EMF radiation from smart meters. Each Smart Meter GUARD is made in the USA, not China, and constructed of high grade stainless steel meshing.



What is smart meter EMF radiation? Smart meter EMF, electro magnetic field, is emitted from your smart meter all day to transmit your power usage data to the utility companies. Once the Smart Meter GUARD covers the smart meter it blocks 98% of the EMF in front and behind the smart meter protecting you inside your home.

User questions & answers

Question:	Will this work for emfs in the home if you do not have smart meter but regular electric house meter
Answer:	Hi, if you don't have a smart meter on your house then there is not need to shield the analog meter you have. This is because analog meters do not use RF, radio frequency, to communicate to the utility company. They come out to your house and physically read your meter. Thanks
Question:	What are the dimensions
Answer:	The dimensions of the Smart Meter Guard is 7 1/2 inches by 4 1/2 inches and is made to mount on the metal ring at the base of the smart meter. Thanks
Question:	Does this block the radiation from getting into the house? Or just outside. What about the interior wal of the house where smart meter is attached
Answer:	There is a video on this from the Smart Meter Guard people. You can find it on youtube. Video title is "Smart Meter EMF Blocked Inside the House". The video shows them installing the meter guard on the outside of the house and of course the reading goes way down. Then someone with a meter goes inside the house and takes a reading. From inside the house, the reading goes up above 7.0 without the guard -- the reading is on the inside wall next to the meter. They put the guard on and it goes down to .1 on the inside wall. So, yes, it is supposed to greatly reduce the radiation on the inside of your house. Don't know more of the details, you can find the youtube video to know more. The video is also on the website for smartmeterguard.com -- I'm sure you can get all the nitty gritty details there.
Question:	Looks way over priced, does it look like one could make it themselves
Answer:	I made 1 out of a stainless steel strainer basket is all. Fits perfectly and does the job. Cost something like $10 is all. The basket is a 8 mesh which is plenty good for shielding. As long as the gaps between the wires are 1/10 - 1/20th of the wavelenth (for 2.4 GHz would be 1/4" or 4 mesh, down to 8 mesh or 1/8"), it will contain the rf radiance. Too fine of a mesh will cause reflection more than absorbtion of rf energy. Saved a BUNDLE! :)
